Patent MX-9702720-A (MX)
Title: Fuel cells employing integrated fluid management platelet technology.
Inventor: SPEAR REGINALD G JR
IPC: H01M8/02
Filed: 1995-10-10
Abstract: Fuel cell stacks (1) comprising stacked separator/membrane, electrode assembly cells in which the separators comprise a series of stacked thin sheet platelets (30-1 and 30-7) having individually configured serpentine micro-channel reactant gas humidification (35, 40), active area (25) and cooling fields therein. The individual platelets are stacked with coordinate features precisely aligned in contact with adjacent platelets and bonded to form a monolithic separator. Post bonding processing includes passivation, such as nitriding. Preferred platelet material is 4-25 mil Ti in which the features, serpentine channels (52), tabs, lands (54), vias (61, 63, 65), manifolds and holes, are formed by chemical or laser etching, cutting, pressing or embossing, with combinations of depth and through-etching being preferred. The platelet manufacturing process is continuous and fast. By employing CAD based platelet design and photolithography, rapid change in feature design can accommodate a wide range of thermal management and humidification techniques. 100 cell H2-O2/Air PEM fuel cell stacks of this IFMT platelet design will exhibit outputs on the order of .75 kW/kg, some 3-6 times greater than current graphite plate PEM stacks.

Title: Consumable asphalt containers and method of reducing fumes from a kettle of molten asphalt.
Inventor: JANICKI RICHARD T
IPC: C08L23/10
Filed: 1997-12-05
Abstract: A consumable container is molded from a composition comprising 40 to 90 weight percent of an asphalt and 10 to 60 weight percent of a polymer material, which advantageously can include a first polymer such as PP that imparts heat resistance and a second polymer such as EVA that imparts toughness and impact resistance. This molded asphalt/polymer material preferably has an unnotched Izod impact strength of at least 2 joules. The container is consumable - it can be melted along with roofing asphalt held in the container without adversely affecting the properties of the asphalt and without requiring undue mixing. The composition also can be used to reduce fumes normally emitted from a kettle of molten asphalt, e.g., as measured by a reduction of the visual opacity of the fumes by at least 25 percent, a reduction of the hydrocarbon emissions of the fumes by at least 20 percent, or a reduction of the total suspended particulates emissions of the fumes by at least 15 percent. The container may be used, e.g., to hold roofing or paving asphalt or a recyclable petroleum-derived material, such as used motor oil. In one embodiment, the container composition may include one or more ingredients to improve the quality of paving-grade asphalt.
Patent MX-9803276-A (MX)
Title: Horizontal-flow oil-sealant-preserving drain odor trap.
Inventor: GORGES DIRMAR L
IPC: E03C1/28
Filed: 1998-04-24
Abstract: Improvements in retention of the oily liquid sealant (20) in an oil-sealed odor trap (10B), for drain applications such as a waterless urinal or anti-evaporation floor drain, are accomplished by making the liquid flow path (22A, 22B) substantially horizontal as a departure from conventional practice of substantially vertical flow. The trap (10B) is structured to realize the substantially horizontal liquid flow path (22A, 22B) and to locate the flow path immediately beneath the sealant layer (20) or beneath a baffle portion (16B) that is sloped such that stray sealant droplets migrating upwardly to the upper surface of the flow path due to their buoyancy will be recaptured and returned to the main sealant layer (20). To accomplish substantially horizontal flow (22A, 22B), the entry compartment can be made to have entry (16D) and exit openings substantially offset from each other. The baffle between the entry compartment and the discharge compartment, which has traditionally been made entirely vertical, is made to have a non-vertical portion (16B) that is preferably sloped for sealant recovery. A sealant sheltering region can be provided in the vicinity of the entry region to prevent catastrophic loss of sealant in the event of high pressure water flushing.

Title: Increased density poly:pyrrolidone prodn. - by compression at defined temp. preserving molecular wt. and allowing melt spinning
IPC: C08G69/46
Filed: 1978-07-07
Abstract: The water content of finely powdered polypyrrolidone is reduced, and the bulk density increased, by compressing material with a water content of 5-60, pref. 10-30, wt. % at between 50 degrees C and its m.pt. pref. 100-200 degrees C, to 3.515-21.1kg/cm2. This gives a solid with a dry (i.e. 1 wt. % water) bulk density of 0.3-0.8, pref. 0.48-0.8g/cm3. The compression is pref. effected by extrusion through a pulveriser to give a ground or granulated product. The process enables polypyrrolidone to be melt spun to fibres, pref. after the water content has been reduced to 0.5-1 wt. %. Ordinarily, because of its low density, this cannot be done unless, e.g., the polypyrrolidone has first been melt extruded to form granules, but this, unlike the new process, causes a loss in mole wt.
